Find the simple interest to the nearest cent.
3.) $2,400 at 3.5% for 5 1/4 years.

$441

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.5%/100 = 0.035 per year,

then, solving our equation

I = 2400 × 0.035 × 5.25 = 441

I = $ 441.00

The simple interest accumulated

on a principal of $ 2,400.00

at a rate of 3.5% per year

for 5.25 years is $ 441.00.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
